## 对默认客户
- **无感**:未显式开通时,不改变现有保存 / 自增表行为。
- `local_dbsync` 为**增值开通**(客户端显式配置);平台**不会**全员切默认。
## 本版本智建已交付
| 能力 | 说明 |
|------|------|
| 通道校验 | UUID TEXT PK + FK 闭包;拒绝自增整数作同步键 |
| Agent API | 拉白名单、push / push batch → 线上 A |
| Binding | `local_database_id ↔ online_db_id` 登记查询 |
| LWW | 默认源端覆盖;超管审计 + 单行回滚;公司 conflicts → 403 |
| 同步修复 | 对账限流(默认 300s |
